Indoor environment design system, indoor environment evaluation system, indoor environment design method, and indoor environment evaluation method

An indoor environment evaluation system for evaluating an environment in a room for radio communication, which comprises:

• indoor environment input means for inputting the environment in said room;
• second signal propagation property calculation means for calculating a signal propagation property in a laboratory of an environment corresponding to the environment in said room inputted by said indoor environment input means, based on a relation between environments in the laboratory of a specific size and signal propagation properties in said laboratory, which is preliminarily obtained experimentally;
• second signal propagation property conversion means for converting the signal propagation property in said laboratory calculated by said second signal propagation property calculation means, to a signal propagation property in said room;
• and
• indoor environment evaluation means for evaluating the environment in said room for said radio communication, based on the signal propagation property in said room converted by said second signal propagation property conversion means;
• wherein said second signal Propagation property conversion means converts the signal propagation property in said laboratory to the signal propagation property in said room, based on comparison between a size of a space in said room and a size of a space in said laboratory.
